PHP5实例:简简单单生成条形码

网络整理 - 07-27

  本文中使用的是PHP5的版本。在使用前注意要将PHP的GD模块开启。在Windows中为php_gd2.dll,Linux中为gd.so。将压缩文件解压到Apache,执行。PHP5生成条形码见下图:

  1. Type:选择条形码类型

  2. Output:输出的图片格式

  3. Thickness:条形码高度

  4. Resolution:条形码大小

  5. Font:条形码下方的文字大小,也可不显示文字

  

  PHP5生成条形码test.php代码:

  

  // Including all required classes require('class/BCGFont.php');

  require('class/BCGColor.php'); require('class/BCGDrawing.php');

  /*'BCGcodabar','BCGcode11','BCGcode39','BCGcode39extended','BCGcode93', 'BCGcode128','BCGean8','BCGean13','BCGisbn','BCGi25','BCGs25','BCGmsi',

  'BCGupca','BCGupce','BCGupcext2','BCGupcext5','BCGpostnet','BCGothercode'*/ $codebar = $_REQUEST['codebar']; //该软件支持的所有编码,只需调整$codebar参数即可。

  // Including the barcode technology include('class/'.$codebar.'.barcode.php');

  // Loading Font $font = new BCGFont('./class/font/Arial.ttf', 10);

  // The arguments are R, G, B for color. $color_black = new BCGColor(0, 0, 0);

  $color_white = new BCGColor(255, 255, 255); $code = new $codebar();

  $code->setScale(2); // Resolution $code->setThickness(30); // Thickness

  $code->setForegroundColor($color_black); // Color of bars $code->setBackgroundColor($color_white); // Color of spaces

  $code->setFont($font); // Font (or 0) $text = $_REQUEST['text']; //PHP5生成条形码将要数据的内容

  $code->parse($text); /* Here is the list of the arguments

  1 - Filename (empty : display on screen) 2 - Background color */

  $drawing = new BCGDrawing('', $color_white); $drawing->setBarcode($code);

  $drawing->draw(); // Header that says it is an image (remove it if you save the barcode to a file)

  header('Content-Type: image/png'); // Draw (or save) the image into PNG format.

  $drawing->finish(BCGDrawing::IMG_FORMAT_PNG);
